Computational Materials Science: Modeling Materials

Predict and understand materials properties from atomistic simulations with powerful computational chemistry tools in the ADF Modeling Suite. The molecular and periodic DFT, semi-empirical approaches and reactive MD modules are easy to use from the integrated graphical interface so you can study,  at various levels of sophistication, the molecular and bulk properties of systems ranging from a few to a million atoms.

A webinar in 2017 highlighted recent papers and new capabilities for materials modeling (see slides and video), focusing for modeling properties of nanoparticles, batteries, and organic electronics.

New Perovskite band gaps, DOS and COOP

This tutorial illustrates how the analysis of density of states (DOS) and crystal-orbital overlap populations (COOP) provides insights about the nature of chemical bonding within crystalline materials. This also reveals starting points for a systematic tuning of the band gap in such crystals which is of paramount importance for photoelectric and optoelectronic applications.
